Question

我正在尝试在地图上绘制lat和long事件数据。

在这段代码中，我需要十种不同的颜色参数才能使它工作，我的颜色已经用完了。我该如何解决这个问题？

lon=[]
lat=[]

def getcolor(c):
    if c in [1970,1980,1990,2000,2010]:
       return 'bo'
    if c in [1971,1981,1991,2001,2011]:
        return 'go'
    if c in [1972,1982,1992,2002,2012]:
        return 'ro'
    if c in [1973,1983,1993,2003,2013]:
        return 'co'
    if c in [1974,1984,1994,2004,2014]:
        return 'mo'
    if c in [1975,1985,1995,2005,2015]:
        return 'yo'
    if c in [1976,1986,1996,2006,2016]:
        return 'ko'
    else :
        return 'wo' # I have run out of color arguments 


def map_year(year):
    count=year
    while count>year-10:
        lon=pd.Series(df.longitude[df['iyear']==count])
        lat=pd.Series(df.latitude[df['iyear']==count])
        x,y = map(lon.tolist(),lat.tolist())
        map.plot(x, y, getcolor(count), markersize=6)
    plt.hold(True)
    count=count-1
    plt.show()

map_year(2016)

更新感谢您的投入.. 现在我在getcolor函数中将颜色格式更改为rgb元组，并将plot命令编辑为：

map.plot（x，y，color = getcolor（count），markersize = 6）

输出是 current ouput

十种不同颜色标记的所需输出是 desired output

请咨询

您可以使用xamarin关键字参数的任何颜色，例如十六进制RGB字符串，如async void OnLoginButtonClick(object sender, EventArgs e) { if (usernameEntry.Text != "" && passwordEntry.Text != "") { var response = GetLoginDetails(usernameEntry.Text,passwordEntry.Text); var getData = await getDataFromService(usernameEntry.Text, passwordEntry.Text); } } public static async Task<HttpResponseMessage> GetLoginDetails(string username, string password) { try { var httpClient = new HttpClient(); HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "http://mywebserverIP/api/Users?Username=" + username + "&Password=" + password); var response = await httpClient.SendAsync(request); return response; } catch (Exception ex) { throw; } } public static async Task<dynamic> getDataFromService(string username, string password) { using (var client = new HttpClient()) { var responseText = await client.GetStringAsync("http://mywebserverIP/api/Users?Username=" + username + "&Password=" + password); dynamic data = JsonConvert.DeserializeObject(responseText); return data; } }。
